The above calculation is within the allowable value, and therefore the selected model can be used.
Select a shock absorber separately.
In an actual calculation, when the sum of guide load factors
Σα
in the formula above is more than 1, consider
decreasing the speed, increasing the bore size, or changing the product series.
